I think the changes in skin color took place 50-30 Kya. The exceptions to the theory would be populations that more recently moved to "wrong" latitudes such as the native Americans. Maybe a white, reflective environment fosters darker skin also, like the eskimos (though they are relatively recent too). I'm just speculating here.
